ALD600/900 Series D.P. Lube (ALD900-20)

ALD600/900 Series D.P. Lube ALD900-20

Lubricator with low lubricating oil consumption.
[Features]
· Centralized control of multi-point lubrication.
· Simplified oil feeding volume setting in which only the pressure differential is adjusted.
· Oil can be replenished by merely opening and closing the oil filler plug without stopping the air line.
· The condition of the generation of micromist can be checked from the oil filler port.
· Accessories: bracket / panel / float switch (for S1 and S2).

Precautions

Caution on Design

*Epoxy resin containing glass fiber and polycarbonate is used in some parts of D.P. Lube and D.P. Lube Unit. These units cannot be used in an environment or in a location that is exposed to synthetic oil, thinner, acetone, alcohol, organic solvents such as ethylene chloride, chemicals such as sulfuric acid or nitric acid, cutting oil, kerosene, gasoline, or a threadlock agent, etc., because they will be damaged.

Piping

  • *The drain pipe for the air filter in D.P. Lube Unit must have a minimum pipe inner diameter of ø6.5 and a maximum length of 5 m. Avoid using a riser pipe because it could cause the auto-drain to malfunction.
  • *If installing an air tank, install it on the IN side of D.P. Lube Unit. If it is installed on the OUT side, the micromist could be arrested by the air tank, which could lead to insufficient feeding of oil.

Mounting/Adjustment

  • *Provide about 30 cm of space above and below D.P. Lube or D.P. Lube Unit to facilitate their maintenance and inspection.
  • *When the line is stopped, do not adjust or set the differential pressure, as it could cause the differential adjustment valve to break.
  • *When setting the pressure differential, if there is a fluctuation in the operating flow rate, set the pressure differential to the lower flow rate range.

Maintenance and Inspection

*Before removing the oil filler plug, loosen it two and a half turns to completely release the pressure inside the case. This will prevent the oil filler plug from flying out.

*See the manufacturer's catalog for product information other than the above.
